Guess what I was trying to say, the trouble with 'one size fits all' stat weights, is they don't work.
The BiS stat weights that are most often quoted have almost no relevance to someone that's in normal raid gear, or pre-raid gear, or two pieces shy of BiS...
BiS profiles have high values in all stats, simply due to the high iLevel; so BiS may say that +Crit will give you the most DPS, but that profile already has a lot
e.g. The BiS Shadow T13H shows Crit > Haste=Mastery, but it has 32.36% Haste! It has no relevance to someone whose Toon is sitting on 20% Haste. If they then went and reforged themselves for Crit > Haste = Mastery, it would surely be a DPS loss, over say, reforging up to 24.97% Haste and then Crit > Mastery.
Best thing to do if you want accurate reforge info, is find out your haste break-points, forge to the closest, and Sim yourself. The beauty is, once you Sim you can plug your personal stat weights into your reforge website and get the perfect reforge.
Here's the lv90 breakpoints. Borrowed from http://warcraft.twintop-tahoe.com/
. Percentages are the same at lv85. 2437 for 24.97% and 3051 for 30.01%
In terms of offering stat-weights, I'm not sure how'd you'd get around this. Maybe offer generic pre-raid/normal/heroic stat weights or reforge hints? Or, suggest stacking Haste until 8085. And a quick Simulationcraft for dummies write-up?
The Twintop site
is suggesting (on August 26th) that below 8085 Haste our stat weighting is:
Int > SP > Haste > Spi = Hit > Crit > Mastery
And once we hit 8085 Haste it's:
Int > SP > Spi=Hit > Crit > Mastery = Haste
Interestingly, at this point we'll be gemming for Haste until 24.97%.
There's way too much information on that site
to compile here, but he has Simcraft data posted to back up the weightings on the previous pages of that link. I spent hours reading through it all, and I'm no theory crafter, but it all makes sense to me. It's basically working the same as it has in Cataclysm - Haste to the break-point and then stat #2 takes over. Only caveat being that every new MoP build things need to be reassessed, but the Twintop author seems to be on top of that.
Props to IV's Class guides though. Easily the best complete Class guides on the net. It's a fantastic resource you're building here!
